Garmin edge explore 2

Swipe down from the map page and the return to start feature is first on the nav list. I just sync all my rides to RWGPS which has the personal heat map feature. After seven years of ebiking, there’s lot of purple lines on the map around here!
I have found out that mine will have a blue line where I have been, I think it's the best I can get, any way to change the color on the trail.
Looked on Google
If I select= > activity profiles>navigation >map>appearance >history line color.
I changed color to red,going to try out today.
